Abstract

The opening has a glass (2) provided with a mobile frame (3), where the glass and the mobile frame are movable with respect to a fixed frame (1). The fixed frame comprises a housing to receive a part of a side edge of the mobile frame. A guiding and supporting unit is utilized for providing rotation of a mobile assembly around a rotation axis (11) passing through the side edge so as to place the side edge of the mobile frame in a closing or releasing position.

Description

The present invention relates to an aircraft opening window, and in particular a cockpit side window intended to be manually operated by a member of the crew. The invention also relates to an aircraft comprising a cockpit (or cockpit) equipped with at least one such window.

There are known opening side windows for cockpit. These windows which are maneuverable from the inside of the aircraft, form openings with very useful functions.

In particular, they constitute emergency exits, air vents of the cockpit to evacuate fumes in case of fire or provide a simple way to see the runway in case of lack of visibility, for example because of an ice dirty frontal.

There is thus known a cockpit window comprising a window fixed on a rigid frame, itself connected to the structure by a locking mechanism adapted to immobilize the window, relative to the surrounding structure of the aircraft in the open position, closed or semi-closed.

A single handle allows all the maneuvers of the window. Thus, from its seat, the pilot, or co-pilot, presses a button for unlocking the handle, turns it, then pulls it backwards to retract the opening assembly formed by the window, its rigid frame and its mechanism.

This assembly is then guided in displacement by a lower rail and an upper rail, which form an integral part of the cockpit structure. For this, the mechanism of the window is connected to the bottom of these rails via at least three rollers. Each of these rollers, completed with a set of rollers in connection with the inner edges of the rails, is carried by a carriage forming a bogie.

However, we note not only that the adjustment of these trucks is complex, this task being time consuming, but also that these trucks have a relatively fast wear requiring maintenance interventions by skilled operators, which are expensive.

Furthermore, this mechanism comprises two hooks placed above the upper amount of the rigid frame of the window, and two other hooks connected to the bogies moving in the lower rail. These hooks can absorb the high-energy impact of a bird's impact on the window by transferring the forces created by this shock to the surrounding structure of the cockpit. The opening assembly is also maintained in the closed position thanks to a principle of buttressing the supports of the bogies.

This principle of bracing is essential to the proper functioning of the opening assembly. Indeed, in addition to this function of maintaining the assembly opening in the closed position, it is an additional security in case of impact to the bird. Under the effect of a shock, we obtain an over-locking of the opening assembly, the opening assembly then tending to lock rather than unlock.

However, this bracing principle has drawbacks, especially in terms of adjustments (games, crushing of the seal around the opening assembly, etc.).

It can be seen, moreover, that the rear amount of the rigid frame of the window has been greatly thickened because of the position of the hooks, and this, in order to be able to withstand the impact of a shock to the bird.

This immobilizing system of the opening assembly, by the number of pieces it requires, and the thickening of the mobile frame that follows, is therefore improvable as to the total weight of the window thus equipped.

During the release of the opening assembly, a first translational movement of this assembly caused by the rotation of the handle is obtained thanks to a link return system and a cardan transmission at the top of the opening assembly.

However, it is known that these universal joints that provide mechanical transmission have several disadvantages, particularly in terms of size, and mass.

The present invention aims to address these various disadvantages by providing an aircraft cockpit window whose original design allows to solve the technical problems posed by the windows of the prior art.

The invention therefore aims at an aircraft cockpit opening window, simple in its design and in its operating mode, robust and having a reduced interior dimensions while ensuring a significant weight reduction compared to the opening windows of the aircraft. cockpit of the prior art.

It also allows manual opening in less than ten seconds for use as an emergency exit without assistance from any other source of energy such as pyrotechnics. Finally, this window resists shock to the bird.

For this purpose, the invention relates to an aircraft opening window comprising at least one window provided with a movable frame, an assembly comprising said movable frame and said at least one window being movable relative to a fixed frame, a body of actuating said moving assembly, a device for opening / closing and locking / unlocking said movable assembly actuated by said operating member and means for guiding and supporting said moving assembly.

The Figure 1 shows an aircraft window according to a preferred embodiment of the invention. This window comprises a fixed frame 1 and a window 2 provided with a mobile frame 3. In a conventional manner, this window 2 and its mobile frame 3 forms a mobile assembly intended to be handled by a member of the crew located at inside the cockpit.

To maneuver this mobile assembly, the crew member has a single handle 4 which is hinged.

The mobile frame 3 of the window cooperates with the fixed frame 1 by links at three points ensuring an isostatic connection between the mobile frame 3 and the fixed frame 1.

Guide and support means allow the opening of the window by disengaging the movable assembly from its closed position, followed by sliding of the movable assembly rearwardly.

The Figure 2 shows the window in such a release position. The first lateral edge 5, which is here the front lateral edge of the mobile frame 3, is received in three housings formed by three stops 6, 7, 8 fixed integral with the fixed frame 1 while the other side edge 9 of this mobile frame 3, here the rear lateral edge, is placed at a distance from the opening 10 delimited by the fixed frame 1.

The displacement of the moving assembly from the release position to the closed position and vice versa, is achieved by a rotation of this assembly about an axis of rotation 11 passing through the front lateral edge 5 of the mobile frame 3 received in these dwellings.

The front lateral edge 5 of the mobile frame 3 being inclined, the axis of rotation 11 is parallel to this front lateral edge to allow it to be received in the housing formed by the three stops 6, 7, 8 fixed on all his height. The mobile frame 3 comprises in its lower part an extension arm 21 allowing the front side edge 5 of the mobile frame 3 to be placed on the axis of rotation 11 inclined.

Preferably, each stopper 6, 7, 8 comprises means for adjusting the play (not shown) between each of the stops 6, 7, 8 and the mobile frame 3 in order to maintain the front side edge 5 of the frame in case of shock to the bird.

As visible to figures 1 and 3 to 5 , the guide and support means comprise an upper rail 12 and a lower rail 13 which are integral with the fixed frame 1. Each of these upper rails 12 and lower 13 comprises a bottom and two sides, the rail thus having a section U-shaped

Lower rail 13 comprises a main rail portion 14 and a secondary rail portion 15 in communication with this main rail portion 14.

The rear lateral edge 9, that is to say the edge directed towards the rear of the aircraft, the movable frame 3 carries a rotational movement between the closed position and the release position. This portion of secondary rail 15 is inclined relative to the main rail portion 14 and has a shape of a portion of a circle ( Figure 4 ).

Each of the guiding and supporting means also comprises a bearing ball 16 ( Figure 3 ) placed at the end of a support member 17 which is itself connected to the movable assembly. Preferably, this support member 17 comprises a main body and a secondary body integral with this main body being movable in translation relative to this main body so that the position of this secondary body relative to the main body can be varied from in order to adjust the position of the moving assembly relative to the bottom of each rail.

Each bearing ball 16 is rotatable at the end of this support member 17, which advantageously allows a bearing of this bearing ball in several directions. Thus only such a ball carrier allows a passage of the curved secondary rail portion 15 to the main rail portion 14 having a different direction.

Each support and guide assembly further comprises a roller 18 to provide lateral guidance of the carrier ball in the lower rails 13 and 12 corresponding upper rails.

A bearing ball 16 is placed at the upper and lower ends of the mobile frame 3 on the side of the lateral edge 5 directed towards the front of the aircraft, of this mobile frame 3, these bearing balls 16 make possible the rotation of the moving set.

The support member of each bearing ball is, for example, made of galvanized steel, the bearing balls being made of stainless steel and the rolling rollers 18 of steel.

One of these support members 17 has been positioned directly below the moving assembly to directly support the effort of the weight of the assembly. More specifically, this support and guide assembly is placed at the rear lateral edge 9 of the mobile frame 3. This support and guide assembly further comprises a lever 19, this lever being rotatable in a parallel plane. at the window sill. At the end of the lever 19, a simple roller 20 is sufficient to create the opening / closing movement of the opening / closing device of the window, resting against the flanks of the lower rail 13.

The flanks of the upper and lower rails 12 and 12 are spaced apart by a greater distance than the diameter of the rollers 18 surrounding the support members 17. The bearing balls 16 having a point contact with the bottom of these rails 12, 13 advantageously comprise a protective surface coating. This bottom can be hardened, for example by ceramization.

The window also comprises a locking / unlocking device of the mobile assembly comprising three locking members 22, or latches, placed only on the rear lateral edge 9 of the mobile frame 3 to lock the movable assembly in the closed position.

With such a large number of locking members 22 and their positioning on the rear lateral pillar of the mobile frame 3, it is advantageously possible to significantly reduce the thickness of the rear side pillar while ensuring a resistance of the window. to the shock to the bird.

Each locking member 22 comprises a movable arm cooperating with a corresponding fixed stop 23 placed on the fixed frame 1 to ensure the locking of the movable assembly in the closed position.

Each movable arm has a flat portion 24 and is provided with a roller 25 at its end. Thus, by a translational movement only, each locking member 22 rolls on the fixed stop 23.

The fixed abutment 23 comprises, on its part which comes into contact with the roller 25 of the locking member, or latch 22, successively a first slope 26, a flat 27 and a second slope 28.

The shape of the fixed stop 23 advantageously allows to find the two functions provided by the bracing principle of the windows of the prior art.

The first slope 26 encountered by the roller 25 ensures the crushing of the seal (not shown) while the second slope 28 prevents the unlocking of the moving assembly in case of impact to the bird. This second slope 28 also allows the flat portion 24 of the bolt to bear directly on the fixed stop 23: the shock to the bird is not taken up by the axis of the roller but by the flat part 24 of the body blocking 22 which then has a stop function.

At the level of the operating member of the moving assembly, and in order to reduce the force due to the reaction of the seal of the mobile frame 3 during its crushing, the seal will preferably be a "self-inflating" seal. This seal is perforated over its entire periphery which allows to significantly reduce the reaction force while ensuring the seal (30% compression).

The control of the locks 22 placed on the rear lateral edge 9 of the mobile frame 3 is obtained by the actuation of the handle 4 connected by a lever 29, with two clutch cams 30, 31 superimposed.

During the first 45 degrees of rotation of the operating handle 4, the latches 22 are actuated by the clutch cam 31, then, for the 90 ° of rotation following the operating handle 4, the other clutch cam 30 controls the release of the moving assembly.

Therefore the unlocking, then the release of the moving assembly are made in 135 ° of rotation of the handle 4.

The latch 22 placed in the lower part of the rear lateral edge 9 is advantageously directly driven by the disengagement cam 31 by means of a connecting rod 32, as to the latch 22 placed in its part. superior, it is controlled by a traction and thrust cable 33 (commonly called ball drive or English "push-pull cable") so that the movement of the lock of the lower part drives that of the lock of the upper part.

A connecting piece (not shown) between the latch 22 of the upper part of the rear lateral edge 9 and the traction and thrust cable 33 makes it possible to add the intermediate lock 22. This connecting piece is just guided in translation on the mobile supervision 3.
